Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Application of M Rakudo The present invention relates to a coin-operated washing machine that allows washing the washing tub before washing.

(C'l Prior Art) In-type washing machines are installed in coin-operated laundry machines for commercial use, but since they are used by an unspecified number of people, they are often unsanitary and contaminated with bacteria. Therefore, although it would be fine if a manager was always making efforts to keep the laundry clean, coin-operated laundromats without a manager are often preferable from a sanitary perspective.

e→ Purpose of the invention The present invention provides a coin-operated washing machine with a VC tank washing switch,
The purpose is to wash the washing tank with water before starting washing to wash away bacteria and maintain sanitary conditions.

B) Structure and operation The present invention provides a tank washing switch in series with a timer contact forming a part of a self-holding circuit for a certain period of time after a coin is inserted.
A relay contact that closes for a certain period of time when the tank washing switch is turned on is connected in parallel with the timer contact n11, and the water supply solenoid valve, drain solenoid valve, and dewatering tank drive motor are simultaneously energized through this relay contact. , water supply, drainage, and rotation of the dehydration tank are carried out at the same time.
The water supplied inside the machine splashes up to the top of the dehydration tank, washes away dirt, and is discharged. In addition, since the dehydration tank has a substantially idling shape, it has good startup performance and can be rotated at high speed in a short period of time, so that the time required for washing the tank is short.

(E) Example The following example will be explained based on the drawings. (1) is a first coin switch that temporarily switches from normally closed contact (NC) to normally open contact (No) K when a 100 yen coin is inserted. % (2) is the relay contact (5eL) of the sixth relay coil (3) that connects the first coin switch (1) through the normally closed device j (NO).
The first relay coil is connected to the normally open contact (No), and when energized, the relay contact (2a) is closed to form a self-holding circuit, and the other relay contact (2b)' is closed to form the third relay coil. (3) is turned on so that it is energized. (
4) is a second coin switch that temporarily closes the contact when a 50 yen coin is inserted, and (5) is a second relay coil connected in series with this second coin switch, which is connected in parallel with the second coin switch when energized. The relay contact (5a) is closed to form a self-holding circuit, and the other relay contact (5a) is closed to form a self-holding circuit.
b) is also closed. (6) is a price setting switch connected in parallel with this relay contact (5b), and when it is open, the price setting is 150 yen or 200 yen, and when it is closed, the price setting is 100 yen.

In addition, when setting to 200 yen, the 50 yen coin slot is manually closed by a tank washing switch, and (8) is a short time timer connected in series with the tank washing switch, and when energized, it is connected in series with the fourth relay coil (9). Close the timer contact (8a). When the fourth relay coil (9) is energized, it closes the relay contact (9a) parallel to the tank washing switch (7) to form a self-holding circuit, and also closes the other relay contact (9).

At the same time, power is applied to the water supply solenoid valve αC through the normally closed contact (NG) and @66 timer contact (10f), and at the same time, power is applied to the drain valve through the top lid safety switch αυ and relay contact (9C), and the relay contact (9c) Also energizes the washing and dewatering motor α through (+; +d). When the current is applied to the V'c water solenoid valve a41, a clutch (not shown) is activated, so that the washing and dewatering tank is simultaneously rotated by the washing and dewatering motor α7)Vc. As a result, water is supplied and drained while the washing and dehydrating tank rotates, so the supplied water immediately splashes and washes away dirt from the entire washing and dehydrating tank in a short time. When washing the tank, the relay contact (9θ) opens, so the hot water supply electromagnetic valve (ltIC) is not energized and therefore no hot water is supplied, but hot water can be supplied by omitting the relay contact (9e). Also, if this relay contact is omitted and a relay contact is connected to the water supply solenoid valve +15H11 at the same time, the sterilization effect will be improved because only hot water will be supplied.When the tank is washed for a certain period of time, the timer contact (8a
) opens, the self-holding circuit is released and the tank condition ends. Also, if you insert a coin while washing the tank, the relay contact (3b
) will open, the tank washing will be stopped and the washing operation will start immediately.

(f) Effects As described above, in the present invention, a part of the self-holding circuit that is activated by inserting a coin is constituted by a timer contact (10g), and the self-holding circuit is cut off after a certain period of time has passed after the start of operation. , the relay coil in this self-holding circuit will not continue to be energized indefinitely and its lifespan will be shortened, and the relay contact (9b) and the timer contact (10g), which are closed for a certain period of time when the tank washing switch is turned on, are connected in parallel. Since it is connected, even coin-operated washing machines that do not start operating unless a coin is inserted can be washed manually. Also, when washing the tank, the dehydration tank rotates while supplying water and draining water, so the water splashes and you can wash every corner of the disease.Also, since the tank rotates when there is little water, this tank can be used for a short time. It can reach high speed rotation and wash the suri in a short time.
